Pear3DEngine is a modern and modular 3D development framework
Pear3DEngine is a modern and modular 3D development framework that lets you create professional games, simulations and more. You are free to develop your program in C + +, XML or LUA and publish it as open source software or selling it as a commercial program. The rendering engine uses internally OpenGL or DirectX optionally. The planned editor supports software development on Linux, Windows and maybe MacOS X. DirectX 9 and therefore Windows XP are currently not supported and support is not...
